Also, they told me they take blood to test for it. Is that the best way to test? The lab you've linked tests urine ..

What is the best way to test? blood, urine, hair?

This lab offers a rather comprehensive metal screening based on hair (http://www.greatplainslaboratory.com...etals_hair.asp) . Does that make sense? I am not entirely sure I will get tested properly and for everything in the local one I've called today.
